Install on AIX

Install on AIX

You can install Splunk Enterprise on AIX using a tar file.

Important: The user Splunk is installed as must have permission to read /dev/random and /dev/urandom or the installation will fail.


If you are upgrading, review "How to upgrade Splunk Enterprise" for instructions and migration considerations before proceeding.

Install Splunk Enterprise

The AIX install comes in tar file form.

When you install with the tar file:

  • Splunk Enterprise does not create the splunk user automatically. If you want Splunk Enterprise to run as a specific user, you must create the user manually.
  • Be sure the disk partition has enough space to hold the uncompressed volume of the data you plan to keep indexed.
  • We recommend you use GNU tar to unpack the tar files, as AIX tar can fail to unpack long file names, fail to overwrite files, and other problems. If you must use the system tar, be sure to check the output for error messages.

To install Splunk Enterprise on an AIX system, expand the tar file into an appropriate directory. The default install directory is /opt/splunk.

For AIX 5.3, check to make sure your service packs are up to date. Splunk Enterprise requires the following service level:

$ oslevel -r

Start Splunk Enterprise

Splunk Enterprise can run as any user on the local system. If you run it as a non-root user, make sure that it has the appropriate permissions to read the inputs that you specify. Refer to the instructions for running Splunk Enterprise as a non-root user for more information.

To start Splunk Enterprise from the command line interface, run the following command from $SPLUNK_HOME/bin directory (where $SPLUNK_HOME is the directory into which you installed Splunk):

 ./splunk start

By convention, this document uses:

  • $SPLUNK_HOME to identify the path to your Splunk installation.
  • $SPLUNK_HOME/bin/ to indicate the location of the command line interface.

Note: The AIX version of Splunk does not register itself to auto-start on reboot. However, you can do so by running the following command from the $SPLUNK_HOME/bin directory at a prompt:

./splunk enable boot-start

This command invokes the following system commands to register Splunk Enterprise and Splunk Web in the system's Subsystem Resource Controller:

mkssys -G splunk -s splunkd -p <path to splunkd> -u <splunk user> -a _internal_exec_splunkd -S -n 2 -f 9
mkssys -G splunk -s splunkweb -p <path to python> -u <splunk user> -a _internal_exec_splunkweb -S -n 15 -f 9

For additional information on the mkssys command line arguments, read "Mkssys command" ( on the IBM pSeries and AIX Information Center website.

Startup options

The first time you start Splunk Enterprise after a new installation, you must accept the license agreement. To start Splunk Enterprise and accept the license in one step:

 $SPLUNK_HOME/bin/splunk start --accept-license

Note: There are two dashes before the accept-license option.

For more information, refer to "Splunk Enterprise startup options" in this manual.

Launch Splunk Web and log in

After you start Splunk Enterprise and accept the license agreement,

1. In a browser window, access Splunk Web at
  • hostname is the host machine.
  • port is the port you specified during the installation (the default port is 8000).

2. Splunk Web prompts you for login information (default, username admin and password changeme) before it launches. If you switch to Splunk Free, you will bypass this logon page in future sessions.
